• allows remote configuration and status requests


Under the HoodHTTP Backends

• parallel is always better than seriel

• since Thruk 1.72 backend connections are parallel by default

• connection pool uses more memory butis way faster

• tweak size with ‘connection_pool_size’

• there are Thruk installations with > 50 backends
